Error: uri is not a valid type for a JSON document

I opened a merge request which fixes this issue by adding a DataDefinitionUriNormalizer class that targets uri data types. I copied this from the DataDefinitionTimestampNormalizer class and modified it.

I set the format to uri per https://json-schema.org/understanding-json-schema/reference/string

Attached is a patch for use with cweagans/composer-patches.

Added a test for this.
